IPC: G06F17/10
Filed: 2000-09-22
Abstract: A method for description and simulation based on organizing data into maps of invariants, the invariants being points of energy balance in a system of interest which is either in a stationary state or in a transitory disturbed state. The method includes identifying invariants in the system of interest by identifying primary sources and sinks of energy, identifying secondary energy sources and sinks coupled to the primary sources and sinks, and coupling all such sources and sinks into a network of transformations (48) organized around nodes being characterized by a locally defined principle of balanced self-organization in a system with both a conservation law and energy dissipation.  Such a system becomes "organized" upon achievement. Associated with each invariant are response rates related to energy transfer rates into and out of the invariants. The invariants are mathematically similar to the critical point (74) found in equilibrium system that undergo second order phase transitions.

Abstract: A fluid transmitting device includes a side cover connected to a pump impeller and defining a clutch chamber between the side cover and an outer surface of a turbine runner, and a lock-up clutch which includes a clutch piston connected to the turbine runner. The clutch chamber is divided by the clutch piston into an inner oil chamber and an outer oil chamber.      In the fluid transmitting device, a dividing means for dividing the inner oil chamber into a primary inner oil chamber section and a secondary inner oil chamber section is provided between the turbine runner and the clutch piston. When a lock-up control device is operated to urge the clutch piston in a clutch switch-on direction, the pressures in the primary inner oil chamber section and the secondary inner oil chamber section are raised in the named order relative to the outer oil chamber.  Thus, the connection responsiveness of the lock-up clutch can be enhanced in a simple structure.

Title: Texture replacement in video sequences and images
Inventor: DUMITRAS ADRIANA
IPC: G06T5/00
Filed: 2002-10-04
Abstract: Systems and methods for reducing bit rates by replacing original texture in a video sequence with synthesized texture. Reducing the bit rate of the video sequence begins by identifying and removing selected texture from frames in a video sequence. The removed texture is analyzed to generate texture parameters. New texture is synthesized using the texture parameters in combination with a set of constraints. Then, the newly synthesized texture is mapped back into the frames of the video sequence from which the original texture was removed. The resulting frames are then encoded. The bit rate of the video sequence with the synthesized texture is less than the bit rate of the video sequence with the original texture. Also, the ability of a decoder to decode the new video sequence is not compromised because no assumptions are made about the texture synthesis capabilities of the decoder.

Abstract: My invention prevents the fishing line from breaking by the unexpected last moment of a fish fight. As it is known, there are very precise brakes in fishing reels, but what often happens is that these brakes become ineffective when you have a short line and the fish is almost out of the water. Often the fish will give one last jerk before it is pulled out of the water. It is at this last moment that the brake in the reel does not function properly and hence this fish is able to break the fishing line and escape. My invention 100% prevents this unfortunate situation from occurring, so that the fish can be pulled out of the water safely.

Title: Belt drive ring cvt coupler
Inventor: YUAN JING
IPC: F16H15/42
Filed: 2001-07-18
Abstract: The invention comprises a belt drive ring CVT coupler. Drive rings (10, 11) are rotatably connected to each end of a frame (15). Belts (21, 22) are trained around the drive rings. The relative spatial arrangement of the axis  of rotation of each set of drive rings is maintained by the frame, which hol ds the drive rings in a pre-determined relationship between the pulley sheaves (101, 102; 201, 202). The drive ring on the driver pulley (100) turns in the  same direction as the driver pulley through frictional contact with the side s of the CVT driver pulley sheaves. The drive ring on the driven pulley side rotates in the same direction to the drive ring on the driver pulley, since they are mechanically connected by the belts. The driven drive ring is then in frictional contact with the sides of the driven pulley sheaves, thereby driving the driven pulley (200). The effective diameter or radius of each pulley is adjusted by movement of the pulley sheaves. Axial movement of the pulley sheaves causes the axis of rotation of each drive ring to move eccentrically with respect to the axis of rotation of its respective pulley.  Since the drive rings are mechanically connected, the drive rings move with the frame as a unit in response to the movement of the pulley sheaves, there by changing the effective gear ratio of the transmission.

Title: Method for producing half-finished products made of aluminium alloys and an article manufactured with the aid of said method
Inventor: FRIDLYANDER IOSIF NAUMOVITCH
IPC: C22F1/04
Filed: 2001-07-30
Abstract: The invention relates to a method for producing shaped half-finished product s and articles made of high-strength aluminium alloys in the form of ribs, fittings, beams etc. used for the aircraft and space engineering and for vehicle building. The inventive method consists in the following operations:  ingot casting, homogenisation and forging thereof; compressing a forged billet, hardening and cold shaping thereof in two stages: 1) stretch flattering with a residual deformation ranging from 1 % to 5 %; 2) three- dimensional bending of the billet simultaneously with local plastic deformation by compression ranging from 1 % to 20 % in coupling zones of elements of the billet which are arranged at an angle ranging from 45~ to 13 5~ in relation to each other. Ageing is carried out in two steps: in the first step, the billet is heated to a temperature ranging between 90 ~C and 120 ~C  during 5-24 hours, in the second step the billet is heated to a temperature ranging between 160 ~C and 190 ~C during 5-20 hours. The inventive method makes it possible to produce long half-finished products having an irregular  shape and made of deformable aluminium alloys having high strength characteristics and crack resistance and a low level of residual deformation s thereby ensuring the production of articles devoidof shrinkage and buckling during mechanical operations.
